Nick Alexander e68b7c0a8f Bug 1543982 - Part 1: Avoid re-configuring from within Gradle. r=emilio
The inline comment explains what is happening here.  The issue is that
client.mk is setting MOZ_OBJDIR (and autoconf.mk is setting CC/CXX and
others) as part of `mach build`, which means that recursively invoking
`mach build` sees a different environment, and that triggers
reconfigure.

In some situations we can avoid this by recognizing that the
environment has changed and setting it back to what it was at the time
of `mach build` before client.mk adjusts it.
